The introduction of the EU Methane Regulation and North America creates an opportunity for operators across the energy and infrastructure sectors to strengthen environmental performance while maintaining operational efficiency. Success will depend on solutions capable of delivering wide-area coverage, reliable measurement, and actionable insights at scale. This is a truck-based methane monitoring service that uses laser-based sensor, GNSS, an anemometer, and integrated software and hardware computing and linked to a cloud-based platform. Using commercially available hardware mounted on a vehicle, it provides passive, continuous emissions measurements as it travels through operational areas. The system’s design allows for seamless integration into existing fleet routes, enabling broad coverage without disrupting day-to-day operations. In independent testing at Colorado State University’s METEC facility (during development and testing), it demonstrated a detection sensitivity of 0.0057 kg/hr with a 90% probability of detection (PoD); a level of performance that would align with the global methane measurement and reporting objectives. The platform has already been deployed in one of the largest methane monitoring projects to date, covering several thousand sites, with additional deployments at gathering systems and midstream operations across North America. These large-scale operations have identified fugitive sources, efficiencies and emission reductions, enabling teams to target repairs where they deliver the greatest impact by triaging and quantifying emissions. By combining high-sensitivity detection with a practical, vehicle-based deployment model, it offers a scalable and adaptable approach to methane monitoring. Its flexibility makes it suitable for a wide range of applications, including the energy sector, gas distribution networks, and municipal systems. This presentation will share operational data from large-scale deployment in Canada, highlight the technical innovations enabling this level of sensitivity and coverage, and explore how similar mobile approaches could help meet environmental commitments and evolving regulatory requirements.
